ARM: shmobile: r8a7779: Stop powering down secondary CPUs during early boot
At .smp_prepare_cpus() time, CPUs 1-3 are still powered down: - The bootloader doesn't enable CPUs 1-3, - Non-boot CPUs are disabled by kexec before starting the new kernel. Hence there is no need to try to power them down again, as it will fail silently with -EIO anyway.
